test: bootdev: scan with a broken high-priority device

Browse Source 
Add bootdev_hunt_fallthrough() test to verify that 'bootflow scan -l'
falls back to a lower-priority bootdev when a higher-priority hunter
fails.

Introduce a simple 'sandbox-bootdev' device for the test. The new
bootdev can be configured to produce an error at the hunting stage.

Introduce new host_set_flags_by_label() API and a flags field to
'host_sb_plat' to simulate a bootdev hunter failure for the test.

Adjust boot{dev,flow} tests which depend on bootdev hunters.
